CENTRIFUGAL MILK-TESTER.

SPECIFICATION forming part Of Letters Patent No. 647,180, dated April10, 1900. Application filed October 18, 1899. Serial No. 733,990. (Nomodel.)

is provided about midway of its height with To all whom it may concern.-

Be it known that I, HARVEY FELDMEIER, a citizen of the United States,residing at Little Falls, in the county of Herkimer, in the State of NewYork, have invented new and useful Improvements in Centrifugal Milk-Testers, of which the following is a specification.

This invention relates to that class of centrifugal milk-testingmachines in which the rotary head carrying the bottle-holders is rotatedby a gear mechanism which is actuated by hand.

The object of my invention is to so construct the casing in which therotary head is arranged and the driving mechanism by which the rotaryhead is rotated that the casing and the driving mechanism are separateand distinct and can be easily assembled and separated.

In the accompanying drawings, consisting of two sheets, Figure 1 is avertical section of my improved milk-tester, the section being takenlengthwise of the driving mechanism. Fig. 2 is a bottom plan view of thesame. Fig. 3 is a vertical section of the driving mechanism on anenlarged scale, the section being taken in line 3 3, Fig. 4. Fig. 4 is atop plan view of the same, partly in section, the section being taken inline 4 at, Fig. 1. Fig. 5 is an elevation of the lower part of thecasing at right angles to Fig. l.

Like letters of reference refer to like parts in the several figures.

A represents the lower part or body of the casing, having the form of acircular bowl rounded at the bottom and provided with supporting-feet a.

B represents the cover, which rests on and closes the casing and whichmay be of any suitable construction.

0 is the rotary head, whichis arranged horizontally within the casingand which carries the pivoted holders D, in which the test-bottles areplaced, which are indicated by dotted lines in Fig. 1. This rotary headand the bottle-holders attached thereto may be of any suitableconstruction. The bottom of the casing is provided with a centralupwardly-projecting or raised annular portion E. This annular raisedcentral portion of the bottom a horizontal shoulder e. The bottom of thecasing is provided with a raised, channeled, or arch-shaped portion E,which extends radially from the raised central portion E of the bottomto the outer side of the casing.

The frame which supports the driving mechanism is arranged underneaththe bottom,

partly within the raised central portion E and partly underneath theradial arch-shaped portion F thereof. This frame and the drivingmechanism mounted thereon are constructed as follows:

77. represents a horizontal frame-bar, which,

is provided at its outer end with a raised hearing h and at its innerend with a similar raised bearing 71?.

I is a vertical open frame, which is formed at the inner end of the bar7t and which rises from the inner bearing 72 and extends upwardlyand'inwardly therefrom. This vertical frame is provided in its lowerportion with a step-bearingc' and in its upper portion with acorresponding bearing 2'.

K is the horizontal driving-shaft, which is arranged lengthwise on thebar h and journaled in the bearings h h thereof. This shaft carries atits outer end a hand-crank 7c and at its inner end, within the verticalframe I, a gear-wheel is. The frame I is provided on one side withhorizontally-projecting lugs Z, in which is journaled a horizontalcountershaft L, carrying a pinion Z and a worm-wheel L. This pinionmeshes with the gear-wheel 7a.

'm is the vertical spindle, which carries the rotary head 0 at its upperend. This spindle is journaled in the bearings i c" of the verticalframe I and is provided between said bearings with a worm or spiral gearM, with which the worm wheel L meshes. These gears are so proportionedthat by rotating the handcrank a rapid rotary movement is imparted tothe spindle and the head, which is mounted thereon and which carries thebottle-holders.

The inner portion of the driving mechanism, comprising the verticalframe I, the coun finer-shaft, spindle, and gears are arranged withinthe open central raised portion E of the bottom of the casing. The upperportion of the frame I and of the spindle project upwardly through thecentral opening of this space of proper depth over the bottom.

The bar his provided near its outer end with laterally-projecting ears71, which fit against lugs it, formed on the under side of the bottom,on opposite sides of the raised or channeled portion F thereof, to whichlugs these cars are secured by screws m The vertical frame I is providedat its inner end with an ear 0, which fits against the under side of theshoulder e of the raised central portion E of the bottom and is securedto said shoulder by a screw 0.

The driving mechanism is supported upon the frame comprising the bar hand the vertical frame I and is entirely distinct and separate from thecasing. This driving mechanism can be constructed in a machine-shop andthe casing in a foundry, and the two parts are assembled by simplyfastening the driving mechanism to the casing. If either part requiresrepairs, they are readily separated. For instance, if a casing shouldbecome cracked it can be readily replaced by a new one without requiringany work on the driving mechanism. This construction also renders themachine very compact and convenient for use.

19 represents an internally-threaded nipple for the attachment of a pipethrough which hot water or steam can be conducted to the casing and thewater can be drained off which falls on the bottom of the casing.

I claim as my invention 1. In a centrifugal milk-tester, the combinationwith the casing having downwardlyprojecting supports on which it restsand having its bottom constructed with a raised central portion, and therotary head arranged in said casing, of a gear-supporting frame suspended from the under side of said casin g and extending along thebottom thereof from the central portion to one side of the casing, and adriving mechanism mounted on said frame and comprising a horizontaldriving-shaft provided at its outer end with means for rotating thesame, a vertical spindle arranged at the inner end of said driving-shaftand connected at its upper end with said rotary head, and

intermediate gearing connecting the inner end of said driving-shaft withsaid spindle, substantially as set forth.

2. In a centrifugal milk-tester, the combination with the casing havingthe bottom constructed with a raised central portion which is open atits top, and the rotary head arranged within said casing, of agear-supporting frame suspended from the under side of said casing andcomposed of an inner raised portion which is arranged within said raisedportion of the bottom and ahorizontal portion extending from said raisedportion outwardly to one side of the casing, a vertical spindlesupported in the inner raised portion of the frame and extending throughthe open raised portion of the bottom to said rotary head, a horizontaldriving-shaft supported in the horizontal portion of said frame, andintermediate gearing connecting said shaft with said spindle,substantially as set forth.

3. In a centrifugal milk-tester, the combination with the casing havingits bottom constructed with a raised central portion, and the rotaryhead arranged within said casing, of a gear-supporting frame secured tothe under side of said casing, and a driving mechanism comprising ahorizontal driving-shaft, ahorizon tal counter-shaft, a verticalworm-spindle, and connecting gear-wheels, substantially as set forth.

4. In a centrifugal milk-tester, the combination with the casing havingits bottom constructed with a raised central portion, and the rotaryhead arranged within said casing, of a gear-supporting frame which issecured to the under side of said casing and which comprises a radialbar and a vertical frame at the inner end of said bar, and a drivingmechanism comprising a horizontal driving-shaft journaled on said bar, ahorizontal counter-shaft and a vertical worm-spindle j ournaled on saidvertical frame, and gear-wheels connecting said shaft and spindle,substantially as set forth.

5. A bowl-shaped casing for a centrifugal milktester having its bottomconstructed with an open raised central portion and with an archedportion extending from said raised central portion to the outer side ofthe casing, substantially as set forth.

SWitness my hand this 14th day of October, 1 99.
